| 摘要 |
The present invention provides a method for producing a block polymer formed by polymerizing at least three polymerizable monomer components, said method having a step (A) of obtaining a first polymer unit by polymerizing a first polymerizable monomer and second polymerizable monomer by living polymerization, and a step (B) of adding, after step (A), a third polymerizable monomer that is different from the first polymerizable monomer and second polymerizable monomer and subjecting a second polymer unit to chain extension. |
